Abstract (en)
[origin: US6437172B1] (Meth)acrylates are prepared by esterifying a high-boiling compound having one or more alcoholic hydroxyl groups with (meth)acrylic acid in the presence of an entraining agent, such as a (cyclo)aliphatic hydrocarbon, by heating the reaction mixture to the boil and discharging the water of reaction with the entraining agent, in a substantially shorter reaction time and constant product quality, if, during the esterification reaction, the entraining agent is metered into the reaction mixture under temperature control at a rate such that the boiling point of the reaction mixture remains constant.
